Embed LIVE Stream

Hello, I'm very sorry if this has already been asked, but I did a search and could not locate this.

I am building a website on
squaredspace.com. I am attempting to embed our live stream that we run through Wowza.
Squaredspace.com has said that I need an iFrame code to embed the feed. Is there such a thing without going through a third party service such as ustream? I'm limited to what I can add, so an iframe code is probably the best option... any help for this novice website builder would be greatly appreciated!
